There are many moving parts to an engine such as bearings, rods and others. All of these, at some point along their movement path, come in contact with other surfaces and must be lubricated. Lubricator parts are used to apply or inject lubrication to help ensure systems work efficiently and with minimal friction that can cause overheating and costly downtime. Typical parts include a grease valve, grease needle, suction tubes, hose pipes, non return valves, and others. A large scale lubrication garage would also stock lubrication containers, penetrants and lubricants, grease guns, and other lubrication accessories.
